Abstract

What is disclosed is a method for making a synthetic veneer, which method comprises impregnating a fibrous web structure with an aqueous dispersion of a finely divided synthetic resin, said dispersion further containing a water-soluble aminoplast resin dissolved therein, and then drying the impregnated web structure by heating it, said synthetic resin being thermoplastically deformable and in a non-crosslinked condition at the beginning of the drying step, but comprising a plurality of groups capable of external crosslinking and which do crosslink during the drying step.
